What furnace repair involves
Furnace repair means finding the point where the sequence breaks: call for heat, inducer, pressure switch, ignition, flame proof, blower. We follow that chain in order rather than guessing at the most expensive part.
Diagnosis and repair of gas, propane and oil furnaces — ignition, flame sensors, blowers, boards and heat exchangers.
What we usually get called for
- Short cycling — on and off every few minutes
- Loud bang or rumble at start-up
- Rooms furthest from the furnace never warm up
- Grinding or squealing from the blower compartment
- Furnace runs constantly but never reaches the set temperature
How we repair it
Most repairs come down to ignitors, flame sensors, pressure switches, inducer motors, blower motors or capacitors, control boards, and gas valves. We show you the failed part and explain what it does before we install a replacement.
When replacement makes sense
We don't condemn furnaces to sell equipment. When a replacement is genuinely the right call, you'll get the reason, the options, and a price — with no pressure to decide on the spot.
Questions from Hemlock Farms homeowners
- Can you come out the same day?
- For a no-heat call we try to, and voicemail gets a same-day callback. Leave your name, address and what the system is doing.
- Do you work on oil furnaces?
- Yes — gas, propane and oil. Say which one you have when you call so the right parts are on the truck.
